CHAS. P. WIGGINS, OF INDIANAPOLIS, INDIANA, ASSIGNOR 'IO CASE, MARSH 85 WIGGINS, OF SAME PLACE.

IMPROVEMENT IN SAWING-MACHINES.

Specification forming part of Letters Patent No. 48,879, dated July 18, 1865.

To all whom it may concern:

vBe it known that I, CHARLES P. WIGGINS, of Indianapolis, in the county of Marion and State ot1 Indiana, have invented a new and useful Improvement on Riders or Guides on Drag- Saws, called Gharleys Improvement;77 and it consists in a double adjustment of it at the Y head and foot to the direction of the saw-plate bar C, to which the slotted and grooved guides D and E are attached for the purpose of directing the motion of the saw-bar F while the same is being reeiprocated by means of the connecting-rod G. The saw H is attached by bolts to the saw-bar F in the usual manner.

The saw-guide J, which rests upon the top of the saw, is attached to the saw-guide frame K by means ot' the. set-screw L. The-slotted foot or pivot bar of the saw-guide frame K K -is adjusted by means of the bolt and nut M operating through the slot in the saine.

The guide-frame K K may be attached to the guide-bar G at T.

The following is the operation.ot' the inachine: Ihe pitman G being operated in the usual manner, the saw-bar F is set in motion, operating in the guides D and E, which are adjusted to cause the saw to move in a direct line to and from the pivot N, which forms the hinge of the guide-bar C. The saw-guide J, being` adjusted to coincide Withthe line of the saw, is rmly held in position by the set-screw L. The saw-guide frame K is then attached to the frame A at M, or to the guide-bar C at T.

It will be secu that a universal or any required lateral adjustment may be effected. The saw-guide frameK, being hinged at S S, allows it to be raised and lowered, still keeping its position upon the saw to prevent its lateral Amotion.

What I claim, and desire to secure by Letters Pat-ent, is-

The arrangement of the saw-guide J, setscrew L, guide-frame K K, with slotted foot or pivot bar S S and M, when constructed and ope-rated substantially as set forth.

CHARLES P. WIGGINS.
